Embodiment
See also Fig. 3, it is the schematic top plan view of rotating mechanism one first preferred embodiment of bearing platform for detection proposed by the invention.In Fig. 3, rotating mechanism 3 is by motor 30, is controlled by motor 30 and the screw rod 31, the end that rotate are fixed in screw rod 31 and the slide block 32 that slides, connecting rod 34 and the crank 35 that an end is articulated in slide block 32 are constituted on slide rail 33, and rotating mechanism 3 is to be fixedly arranged on the base station ST.Wherein, crank 35 is to utilize an end and be articulated in the other end of connecting rod 34 and utilize the other end and be fixed in plummer 36.
Wherein, when motor 30 actions, screw rod 31 rotates to promote slide block 32 and slides on slide rail 33, make connecting rod 34 pivot with respect to slide block 32, be in ten degree with an interior angle and make crank 35 and plummer 36 rotate simultaneously with respect to base station ST, accept test for the determinand that is carried on the plummer 36, so-called herein crank 35 and plummer 36 rotate simultaneously with respect to base station ST, be meant that plummer 36 is rotated according to the rotation center 361 of plummer 36, and an end of rotation center 361 is to be fixed on the base station ST, and the other end of rotation center 361 is to articulate plummer 36.Because the other end of crank 35 is to be fixed in plummer 36,, crank 35 and plummer 36 will be rotated according to rotation center 361 so move when making that connecting rod 34 pivots when slide block 32.The scope that is noted that above-mentioned this angle of what is called is meant that crank 35 and plummer 36 are for the distance that slide block 32 slides on slide rail 33; That is the distance range that slides on slide rail 33 with slide block 32 is a benchmark, and the angular range of crank 35 and plummer 36 rotation with respect to base station ST and simultaneously is in ten degree.
What deserves to be mentioned is that screw rod 31 is via a not shown shaft joint (Coupling) that goes out and be controlled by in motor 30.Rotating shaft, the other end of the affixed motor 30 of one end of this shaft joint then are fixed in screw rod 31.When motor 30 action, drive this shaft joint by the rotating shaft of motor, drive screw rod 31 by this shaft joint again and rotate.
In addition, connecting rod 34 is to be articulated in slide block 32 with rotary joint, and crank 35 is to be articulated in connecting rod 34 with rotary joint; That is to say that when making that at screw rod 31 promotion slide blocks 32 crank 35 and plummer 36 rotate simultaneously, the pass festival-gathering between connecting rod 34 and the slide block 32 is rotated, the joint between crank 35 and the connecting rod 34 also can be rotated thereupon.
Compare with aforementioned TaiWan, China patent I302862 and I233847, the present invention has used slide rail, and screw rod only is subjected to axial force and can not be subjected to the influence of side force, therefore can not produce distortion and influences precision.
See also Fig. 4, it is the schematic top plan view of rotating mechanism one second preferred embodiment of bearing platform for detection proposed by the invention.With Fig. 3 different be in, on slide rail 33, be provided with a slide block 32 ' more, and utilize web member 37 that slide block 32 and 32 ' is connected into a slide block group.This measure can make that the slip of slide block group 32,32 ' on slide rail 33 is more straight, the precision in the time of can significantly promoting connecting rod 34 and drive cranks 35 and plummer 36 and rotate simultaneously.
See also Fig. 5, it is the schematic top plan view of rotating mechanism 1 the 3rd preferred embodiment of bearing platform for detection proposed by the invention.With Fig. 4 different be in, in Fig. 4, utilized an end to be articulated in the connecting rod 34 of slide block 32 originally, also can utilize this end to be connected in slide block 32 ' instead, at this moment, 32 of slide blocks are played the part of the role of the slip that is used for stablizing the slide block group, the chance of screw rod 31 lateral deformations that its screw rod 31 cornering forces that can reduce screw rod 31 suffered connecting rods 34 passbacks are caused.
In sum, the advantage of the rotating mechanism of bearing platform for detection proposed by the invention is, owing to used the collaborative start of crank, slide rail and connecting rod, the running accuracy of itself is much larger than running accuracy and the reliability of belt, so can be because of the angle of the problems affect plummer of running accuracy.
The present invention can be designed and made various corresponding changes and distortion by person skilled in the art scholar, but all is no more than the claimed content of claims.
